Clinically suspected concomitant spinal cord and vertebrobasilar infarctions caused by fibrocartilaginous embolism.

Fibrocartilaginous embolism (FCE) is a rare and probably under diagnosed cause of spinal cord infarction presumably due to acute embolization of nucleus pulposus fragments into the spinal circulation. Concomitant cerebral involvement is much rarer and often asymptomatic. Although the definitive diagnosis is histologic, certain criteria have been proposed to support the diagnosis in living patients, such as absence of vascular risk factors, acute onset or antecedent of valsalva maneuver before the episode and the exclusion of potential differential diagnoses. A 56 years-old patient, without any medical history was referred for sudden back pain while carrying heavy load at work. Clinical examination showed a Brown-Sequard syndrome. Brain and spine MRI disclosed spinal cord infarction at the C4-C5 level associated with brain infarctions involving exclusively the vertebrobasilar circulation. The exhaustive etiological assessment was normal. In our case, the acute symptoms onset, the clinical and imaging data and lack of evidence for other plausible diagnoses in the setting of a valsalva-like maneuver are highly suggestive of FCE diagnosis.
